Hi,the outbound mail servers of tu-chemnitz.de (134.109.228.11, 134.109.228.40) are blocked by *.protection.outlook.com. Unfortunately I can't see the cause on Smart Network Data Service ("All of the specified IPs have normal status."). I sent some support forms (https://support.microsoft.com/de-de/supportrequestform/…) but the automated answer doesn't help us (was in German, meaning "The occurrence of errors is unlikely …")
Is anybody able to help to get in contact with a human being at Microsoft's e-mail services?
Yes, we had a phishing and (by abusing accounts) later spamming incident during the Christmas holidays. We took some technical measures to avoid this in the future, more to follow.
